SAW-S ET.

SPECIFICATION forming part of Letters Patent No. 636,168, dated October31, 1899.

Application filed July 2 '7, 1 8 9 9.

To all whom it may concern.-

Be it known that I, MATTHEW ODGERS, a citizen of the United States,residing in Philadelphia, Pennsylvania, have in vented certainImprovements in SaW'Sets, of which the following is a specification.

The object of my invention is to provide a simple form of saw set inwhich the saw is firmly clamped at a point adjacent to the toothed edgebefore the action of the settingdie upon the tooth, whereby the teeth ofsaws of different sizes can be accurately set. This object I attain inthe manner hereinafter set forth, reference being had to theaccompanying drawings, in which- Figure 1 represents a longitudinalsection of a saw-set constructed in accordance with my invention. Fig. 2is a transverse section on the line a a, Fig. 1; and Fig. 3 is anenlarged face view of the anvil forming part of the saw-set.

The body 1 of the saw-set is hollow and forms a guide for the twosliding dies 2 and 3, the former of which is a clamping-die and thelatter a setting-die, operating in conjunction with an anvil 4, which issecured by a set-screw 5 to a jaw 6, which is located some distancebeyond the end of the body-1 of the saw-set and is connected thereto bya curved arm 7, so that between the body 1 and the jaw 6 is' formed athroat for the reception of the toothed edge of the saw-blade. The anvil4 has a series of setting-faces 4, four of which are shown in thepresent instance, each of these setting-faces having an extent of beveldiffering from the others, as shown in Fig. 3, so that by turning theanvil in respect to the jaw 6 any desired setting-face 4 of the seriesmay be brought into position to coact with the setting-die 3.

The inner end of the body 1 has depending flanges 8,between which arepivoted,by means of transverse pins 9, a pair of levers 10, the shortarms of these, levers engaging with notches or recesses in the outerfaces of the sliding dies 2 and 3, which are disposed back to back inthe central opening of the body 1, as shown in Fig. 1. The long armsofthe levers 10 form handles whereby the saw-set is manipulated, and theselong arms of the levers are normally separated from each other SerialNo. 725.296. (N0 model.)

by the action of an interposed coiled spring 11, so as to withdraw thedies 2 and 3 to their full extent. Contact of lugs 12 on the levers 10with stops 13 on the body of the saw-set serves to limit the separationof the levers and the retraction of the dies.

To pins projecting from the sides of the body 1 of the saw-set are hungprojecting ears 14 on gage-bars 15, located one on each side of saidbody, said gage-bars being connected by a cross-bar 16, which has athreaded opening for the reception of a set-screw 17, the latter bearingupon the rear face of the body 1, so that by the adjustment of thisset-screw the gage-bars 15 can be caused to project more or lessforwardly into the throat of the sawset, and can thus govern the set ofthe tooth by limiting the extent to which the latter is permitted toproject over the beveled face of the anvil 4.

By the use of the clamping-die 2, working closely adjacent to thesetting-die 3, the saw is clamped at a point close to the tooth beforethe action of the setting-die upon the latter.

also simple in construction and convenient of manipulation.

Having thus described my invention, I claim and 'desire to secure byLetters Patcut-- 1. The combination in a saW-set,of the body having ajaw located beyond the end of the same, and an arm connecting said jawto the body, and a setting-anvil on said jaw having a broad flatbearing-surface for the saw-blade and a beveled surface for determiningthe set go of the tooth, and a pair of dies disposed back to back andguided in said body of the sawset, one of said dies being a clamping-diefor the saw-blade and having a flat end opposed to the flat face of thesetting-anvil and the other a setting-die having a beveled end operatingin conjunction with the beveled face of the setting-anvil, substantiallyas specified.

2. The combination in a saw-set, of the hollow body having clamping andsetting dies I00 guided therein, the end jaw having a settinganvilthereon, an arm connecting the end jaw levers, and lugs on the leversprojecting 1011- gitudinally beyond said short arms and coop- I5 eratingwith stops on the body of the saw-set for limiting the extent of suchseparation, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of 20 two subscribing Witnesses.

MATTHEW ODGERS.
